摘要：

In a systematic examination and comparison of two different tantalum starting liner cones and corresponding recovered slugs and jet fragments for detonated shaped charges, using light and transmission electron microscopy observations, the slug and jet grain sizes were reduced from the liners by nearly a factor of 100. The slug and jet cross sections exhibited different concentric zones of varying grain and substructures, and these also varied with a difference in the starting liner cone grain structure. These observations provide unambiguous evidence for dynamic recrystallization as a prominent mechanism for deformation in the detonating shaped charge.
